To all'wlwmit may concern. Be it known that I, PATRICK J. HUssEY, a citizen of the United States, and resident of the city of New York, borough of -Man.- hattan, county of, New- York, and State of New York, have invented a newand limproved Valve, of which the. following 1s a full, clear, and exact description. In connection with valves, and more particularly such valves as utilize a ball body, it is well appreciated that difliculty has been experienced, incident to the valve chattering, particularly when the same has become worn, or when low pressure'isen'countered.

Furthermore, the hemispherical body of the valves, as heretoforeused, had resulted in the production of'a fluid jet which was divided, this-being objectionable vfor a number of well'known reasons.

Also in most types of ball controlled valves, the objection has been noted that the flow is limited, incident to the fact that the valve seat opening is restricted in size, so as to be capable of efliciently co-acting with the bell constituting the valve.

With thisin mind, I haveconstructed a valve in which any objection incident to chatter will be avoided, and by means of I which the jet fluid discharge from the valve will be solid, aside from the fact that'the size of the jet will be only limited bythe cross sectionalarea of the intake anddischarge openings, of the valve.

Further objects of my invention will apar in the subsequent specification, taken 1n connection with the accompanying drawings, which latter present one practical embodiment of the same, and in which;

Figure 1 is a sectional side view of a valve constructed in accordance with ,my inventlon, and

Figure 2 is a sectional transverse view taken; along the line 22 and looking in the direction of the arrows in Figure 1.

Figure 3 is a plan view of the packing box cap, and j Figure 4 is a sectional plan view taken along the line 4.4:.and looking in the direction of the arrows in Fig. 1.

Primarily it will be'noted that in the embodiment illustrated,,I have shown'- my valve as forming part of a faucet, but it is-to be' appreciated that my invention is not necessarily limited to this adaptation. Furthermore, the valve housing 5 may be of any desired type. and a packing'box cap Specification 6': Itetters Patent.

described, is as- 7 sociated with the same, it being also noted that the handle 7 and stem 8 -may be of any customaryconstruction. I ;Contrary tothe conventional construction however,'it will be noted that the valve seat 9 within the housing 5 is of an area substantially equivalent to the intake and discharge openings of the .housing thus overcoming any objection incident to the jets of fluid being restricted in size.

Also the ball 10 co-operating with the seat 9 is obviously of a greater diameter than the seat, and consequently is also larger than the intake and discharge openings forimng a part of the housing. .Thus any danger of the ball becoming wedged within the body of the housing is eliminated, it being only possible to effect a removal of the ball by disengaging the packing box 6.

With a view of avoiding a dividing of the jet discharge from the outlet opening of the .valve, it will be noted that I subdivide the discharge opening 11 within the housing by means of a bar 12 thus forming a cage for the ball 10, and it is thus to be noted that the bar 12 will cause a convergence of the particles of fluid forming the jet, thereby to produce a solid jet which is discharged from the outlet opening of the housing 5. v

To now provide means which will serve to eliminatea chatter of the parts uponthe same becoming worn, or incident to low pressure, it will primarily -be noted that, due to the structure aforedescribed, that a movement of the ball 10 is limited to motion directly away from or towards the seat 9, thus overcoming any difficulty in this connection.

Furthermore, the .packing box cap 6 is extended, as has been indicated by the reference numeral 13, andthis extended portion is formed with screw threads 14 permitting of a tightening nut 15 being mounted thereon. Also it will be seen that the extended portion 13 is split, as has been indicated by the reference numeral 16. and that the body of the same is tapered. Thus, upon the nut '15 being tightened, it will be seen that the parts constituting the upper portion of the cap 6 will be caused to contract, whereby to firmlyembrace the stem 8.

Also the cap 6 is formed in the usual manner with a bore, which accommodates the stem 8, and this bore is screw-threaded so that a co-operation with the screw threads 17 of the'spindle' may be effected, in being "noted that these latter screw threads termi- 'nate at a point well above' the interior of will co-operate with thesame to effectually prevent any chattering of the parts incident to the reasons named;

. Thus I have provided a valve which will.

incorporate'all of the advantages of aball valve in that the only portion of the entire valve upon which any perceptible wear takes place is the inner end of the stem 8, but it will be noted that by means of my improved construction that the disadvantages heretofore associated with a ball valve are eliminated as aforestated, and it will be appreciated that obviously numerous modifications of structure might readily be resorted to without in the least departing from the spirit of my invention, which I claim as, follows f 1. A valve, including a housin ,a' cap seceured to said housing, an exten ed portion forming a part of said ca said extended portion being tapered and ormed of a plu-' rality of sections, a nut adapted to embrace said extended portion, and-a screw threaded valve stem adapted to extend through a screw threaded bore in said extended portion.

its entire length, a valve stem extending through a bore in said cap, the extende portion of said cap being formed with screw threads and a nut adaptedto encircle said extended portion and to be mounted upon said screw threads soas to cause said ex- I tended portion to firmly embrace said stem.
